Bulky controllers can clutter the dash and hit your knees, but this one stays completely out of sight. The main unit—just 3-3/8" long x 3" wide x 7/8" thick—mounts under the dash with an adhesive pad or zip ties. Only your smartphone is visible for control, keeping your interior clean and clear. The internal 3-axis accelerometer senses direction at any angle, so it works smoothly no matter how you mount it.
Hardwiring isn’t needed thanks to the included custom-fit harness. It plugs directly into the factory port under the dash and connects straight to the Echo unit. Pair your phone via Bluetooth in about five seconds, plug in the trailer’s 7-way connector, and calibration finishes automatically. When the LED turns green, you’re ready to tow.
The internal accelerometer measures how quickly your tow vehicle slows down and sends matching power to the trailer brakes. Whether tapping lightly or braking hard, everything stays in sync. The proportional system works with trailers up to 4 axles (8 brake assemblies) and supports electric trailer brakes for consistent, even stops.
Instead of knobs or screens, you run it all through the OneControl app on your smart device (Apple 5.0 or newer, Android 4.3 or newer). Set max output, adjust sensitivity, and hit manual override right from your screen. The outer ring shows real-time brake output while you drive. You can even store multiple trailer profiles so your favorite settings are ready each time you hook up.
If Bluetooth ever disconnects, braking continues using the most recent settings—so safety isn’t interrupted. LED indicators on the unit make troubleshooting simple, while reverse polarity and short circuit protection guard against wiring faults. With its limited lifetime warranty on the controller and 1-year warranty on the harness, it’s built for reliable towing trip after trip.

Ratings & Reviews
Worked great. Helped me to trace down a wiring issue with my wiring on the truck and then worked perfectly and controlled some of the heavier loads and was easy to use.
Sherry was extremely friendly and very helpful when I had questions about the correct fit for my truck. She got me the information I needed and took my order and the parts shipped the same day. I was amazed at how fast I got my order.
Easy to install once you dig out its connector from under the dash. H Ave the unit completely hidden.
The brake controller video was very helpful. I made my choice, ordered it and received free of confusion. Thanks go to etrailer.
Installed the controller under the dash out of the way. Downloading and setting up the app was easy. I have set a profile for my trailer loaded and empty. This is a nice feature.
The app stays open while driving, so the manual brake button is visible, and easy to access, if needed.
Product arrived as scheduled. Enjoyed the tracking access to follow the delivery. I have not had the opportunity to install but I am sure everything will go as planned because of the installation video.
Great product and easy installation. I actually installed in the small shelf right below the controls for the seats on my 13 Ram 1500 Longhorn. Looks very neat and functional. Quick shipping.
This is a DIRECT FIT for my 2014 Ram 1500!! I mounted the controller at the bottom of the center console and everything was perfect! The directions were easy to follow and the installation was a breeze!
The Curt Echo is now on my Nissan Armada and works perfectly. It was an easy hookup with the supplied harness and does its job.
electric brake control
for 2014 ram 1500
this Curt electric brake control unit and harness fit great .
half hour and it's finished.
Don’t even know it’s there, set it and forget it.
This is the old obsolete model of Curt Echo which has to be installed under the dashboard. The newer version, which attaches to the electrical system in the rear of the vehicle, is superior and now preferred by most trailer owners. The above version should be taken off the catalog.
This is my first proportional brake controller. Stopping is much smoother without sacrificing safety. Communication by bluetooth makes for a clean installation.
This controller took me literally 15 minutes to install with the required pigtail and my Rubicon with factory towing package installed. When I initially downloaded the app and connected, it actuated and locked the brakes. I simple deleted the app and reinstalled and everything worked normal.
Was not aware this device draws on the battery constantly. I don't daily drive my truck and have had to replace the battery twice in one month due to being drained below the point where they could be recharged. $[XX] later and this controller removed, I've not had any problems with the battery
This brake controller has to be unplugged when not in use or it drains the battery in a few days. I had to have a electrical test done in my vehicle ($XXX). The etrailer tech said the test was done incorrectly. The Chevy dealer claims it was accurate. I’m left with a problem.
Needed a brake controller I could rely on because I was pulling my camper to a site at the top of a 25% grade within a few days. Unit plugged right into the harness for the factory brake controller (with the adapter cable) on my 2014 Ford F-150,and worked perfectly. Bluetooth connectivity works through the app (rather than through the phone's "settings" icon),and connects instantly. I'm very pleased with this product.
Installed on a 2014 dodge ram 1500... The wires took literally 2 seconds to find under the dash, per etrailers instructional video, and took another to 2 seconds to clip on the pigtail. Hooked up the brake controller and powered up fine. Haven't got a chance to use it yet since the car hauler is about 400 ft back on the property and I got the truck stuck going back to try and get it. Its awdul muddy here in michigan in April. Hopefully some warm weather soon so I can get to it and try this controller out! I ordered it on Wednesday, did 2nd day shipping and called to insure I could receive it by Friday, the lady on the phone had them ship it, within ten minutes I had a confirmation email.
As first time truck and pop-up trailer users, we initially purchased a cheaper brake controller that required drilling the dash. This is a new truck, so we decided to switch and spend more for the Bluetooth. etrailer was easy to work with for a return, and the Bluetooth brake controller is fantastic - so easy to use with our new trailer!
I really wanted a trailer brake controller that I didn’t have to stick an ugly knob/box hanging off my dash. This was my solution and it works perfectly. Plugged right into my Honda Ridgeline existing plug, and easily connected to the app on my phone. Nice setup.
I was looking for a trailer brake controller that did not require a permanent mounting to the dash or center console of my 2020 Jeep Grand Cherokee Trailhawk. I initially considered the wireless bluetooth controller from Curt Echo that plugs directly into the 7-pin outlet next to the tow hitch. However, reviews from individuals that tow RV trailers identified that particular option prevents the 12v battery on the trailer from charging off of the TV while connected. This would limit the RV utilization during long trips involving boondocking.
The Curt Echo under-dash controller seems to solve that problem and uses the same user interface as the Curt Echo.
Easy to install and operate; problem solved!
Easiest install ever !
Plug and play. App is easy understand and use.
My favorite is with the app and on selected active profile you can see the amount of brake amount is being applied to the trailer when the vehicle brakes are applied. I also install the manual override button. FYI: you don’t need the app on your phone open for the controller or the manual override button to work. Also another nice feature of the manual override button is the size about the size of a quarter, uses a CR2032 battery and the battery level is displayed in the app.
This was relatively easy to install under the dash of our 2021 Jeep Grand Cherokee, especially since ours has the factory Trailer Tow Package and therefore an existing pigtail connector ready to connect to the brake controller. The Curt wiring adapter made it super easy to connect the Brake Controller to the vehicle's wiring harness. The controller was easy to calibrate and worked seamlessly while we're towing a rented trailer. We used a dedicated (older) cell phone to operate it while we're towing to avoid any potential interference from other apps rather than using our regular phone on which we receive phone calls texts, etc. This was our first time towing a trailer and this easy-to-use Brake Controller helped make us feel safe and comfortable. Highly recommended.
Do not buy either the Curt Under-Dash or plug-in Wireless brake controllers until Lippert fixes the phone app. I’ve used both happily with the old ECHO Smart Control app. I could use the remote manual button with the phone app not even running. As one would reasonably expect the button talked to the controller directly via Bluetooth. The new OneControl Auto app must be running and in the foreground to use the manual remote! And the most recent version of ECHO Smart Control is non-functional, it just tells you to install OneControl Auto.
The break controller worked seamlessly. Profiles are easy to set up and it has very reliable Bluetooth connectivity with my phone. Installation was really easy on my Honda Pilot!
